Snug fit
Initially ordered the size small. Had this changed to large after trying the sizes at the shop. From experience Giro sizes are small for their gloves. Size medium does fit but is limited with the tightness between thumb to the index finger. I have had this with other Giro gloves where this area will become undone from the seams over time. The restriction is noticeable when you are reaching for your drop handlebar leavers when changing gear. This is the reason why size large was chosen in the end and remedies this restriction between thumb and index finger. Nice all round gloves suitable for winter windy rides.
